I'm still a novice modder. But I think I've picked up a general rule from the experts: Take a look at the file se4\data\components.txt. If you see a weapon in there that has an ability like 'Destroy weapon' and a value of 'Missile Weapon'. Then, you *might* be able to modify the file to add a component that destroys some other type of weapon. But if you cannot find that ability in the components.txt or the abilities.txt file, then the game probably doesn't support it.

The best fit for what you are asking is the Tachyon Projection Cannon. It has a line that says:
Weapon Damage Type := Only Weapons

But it doesn't have anything in there about specifict weapons. So, I'm guessing that you can't make a weapon that only destroys certain weapons.

The same principle applies to your great idea for a component that produces limited supplies each turn. If there was already a component in the file that generates, for example, 50 supplies per turn, then you could modify the file to make it produce 150. But I don't see anything in the file that produces supplies except the components that require a star.
